Mengimbas pekali transformasi terkuantisasi ialah alat penting untuk pengekodan video. Sebagai contoh, pengekod video MPEG-4 menggunakan tiga imbasan berbeza untuk mendapatkan kecekapan pengekodan yang lebih baik. Kertas kerja ini mencadangkan imbasan taburan pekali sifar adaptif dalam pengekodan antara blok. Kaedah yang dicadangkan cuba menambah baik pengekodan pekali sifar H.264/AVC dengan mengubah suai operasi imbasan. Memandangkan taburan pekali sifar diubah oleh kaedah imbasan yang dicadangkan, jadual VLC baharu untuk elemen sintaks yang digunakan dalam pengekodan panjang pembolehubah penyesuaian konteks (CAVLC) juga disediakan. Penjimatan dalam julat kadar bit daripada 2.2% hingga 5.1% dalam kes kadar bit tinggi, bergantung pada urutan ujian yang berbeza.

Abstract: Scanning quantized transform coefficients is an important tool for video coding. For example, the MPEG-4 video coder adopts three different scans to get better coding efficiency. This paper proposes an adaptive zero-coefficient distribution scan in inter block coding. The proposed method attempts to improve H.264/AVC zero coefficient coding by modifying the scan operation. Since the zero-coefficient distribution is changed by the proposed scan method, new VLC tables for syntax elements used in context-adaptive variable length coding (CAVLC) are also provided. The savings in bit-rate range from 2.2% to 5.1% in the high bit-rate cases, depending on different test sequences.
